Vinyl RPM Pitch Calculator
Calculate pitch change from RPM variations
About this calculator
The Vinyl RPM Pitch Calculator determines how pitch changes when vinyl records are played at different speeds than their intended RPM. This tool is essential for DJs, music producers, and vinyl enthusiasts who need to understand how tempo and pitch alterations affect their recordings. Whether you're beatmatching tracks, creating unique remixes, or analyzing vintage recordings played at incorrect speeds, this calculator provides precise pitch change measurements in cents and frequency ratios.
How to use
Enter the original RPM of your vinyl record (typically 33⅓ or 45 RPM) and the actual playback RPM. The calculator will instantly show the pitch change in cents and as a frequency multiplier. Positive values indicate higher pitch, while negative values show lower pitch than the original recording.
